Description

Technical Field

[0001] The present invention relates to the technical field of slides, and in particular to a forming die for high-strength connectors of a combined stainless steel slide. Background Art

[0002] The combined stainless steel slide provides entertainment and leisure functions for people with its advantages of good weather resistance, long service life, and the ability to customize styles, shapes, and lengths according to customer needs. In the combined stainless steel slide, the high-strength connectors play a key role in connecting various components and ensuring the structural stability and safety of the slide. The existing stamping forming is to apply external force to a stainless steel plate by the lower die base of the upper die base, so that it undergoes plastic deformation or separation, thereby obtaining a workpiece with the required shape and size. For the flange connectors of the combined stainless steel slide, the stamping die forming uses the die to process the stainless steel plate to make it into a flange ring connector with a specific shape, so as to connect and fix the connection part of the combined slide.

[0003] When the existing forming die for high-strength connectors of a combined stainless steel slide performs stamping forming, first place the metal thin plate to be processed in the processing groove of the lower die base. Driven by the stamping equipment, the punch of the upper die base presses down to make the thin plate stamping formed. After stamping, the upper die base lifts, and the ejector part moves upward under the action of external power to eject the formed workpiece from the processing groove, which is convenient for the operator to take away. The stainless steel plate is placed between the lower template and the upper template. During the stamping process, the middle part of the stainless steel plate is impacted. Since there is no limit on both sides of the stainless steel plate, the stainless steel plate is prone to deviation during the stamping process, which easily leads to a reduction in the stamping accuracy of the stamping forming die, and thus leads to a reduction in the quality of the ring connectors at the high-strength connection part of the combined stainless steel slide.

On one side of the pressing spring 94, there is a material pushing plate 95 which is used to push out the waste materials. On the other side of the sliding member, there is a reset member 96.

The rack two 961 is meshed with the gear two 962 to ensure that the material pushing plate 95 can be accurately positioned at different working stages and prepare for the next waste material cleaning.

[0022] In this embodiment, during specific use, first, a stainless steel plate is sent from the front of the upper die base 1 and the lower die base 2 by a robotic arm or other feeding components and then placed on the top surface of the lower die base 2. Since a driving component is provided at the top end of the upper die base 1, the driving component drives the punch inside the upper die base 1 to move downward. The upper die base 1 achieves a buffering effect with the help of the buffering component 5, prompting the stainless steel plate to be stamped and formed through the processing groove formed on the top surface of the material ejecting component 4, thereby preventing the stainless steel plate from shifting. Deviation correction structures 7 and limit correction structures 8 are arranged on both sides of the material ejecting component 4 to achieve the purpose of correcting the offset stainless steel plate, ensuring the accuracy of the plate placement position and laying a foundation for subsequent stamping and forming. The setting of the buffering component 5 can effectively relieve the impact force when the punch presses downward, prevent excessive damage to the stainless steel plate, and improve the forming quality of the plate. The prior arrangement of the deviation correction structure 7 and the limit correction structure 8 can perform a full-range position calibration on the plate before stamping, greatly reducing the rejection rate caused by plate offset and improving production efficiency; Such as Figure 4, as the driving component drives the punch inside the upper die base 1 to move downward, when the upper die base 1 moves downward below the middle base 3, the upper die base 1 squeezes the rubber plate 710, the rubber plate 710 squeezes multiple buffer springs 79 at the bottom, and the multiple buffer springs 79 squeeze the connecting plate 78 to make it move downward. The connecting plate 78 drives the sliding plate 711 on one side to slide downward in the groove 713 opened on the surface of the vertical plate 712. The downward sliding of the sliding plate 711 drives the first spring 714 connected to the top to stretch and store energy. The bottom end of the vertical plate 712 is fixedly connected to the base 3, and the base 3 is fixedly connected to the workbench through bolts. The connecting plate 78 squeezes the inclined plate 77 to make it move downward. The inclined plate 77 pushes the connecting block 74 at the bottom through the connecting seat 76 to slide toward the stainless steel plate in the notch 73 opened on the surface of the rectangular block 72. A second spring 715 is arranged on one side of the connecting block 74, and one end of the second spring 715 is connected to the notch 73. The bottom end of the rectangular block 72 is fixedly connected to the top end of the extension plate 71, and the extension plate 71 is fixedly connected to the lower die base 2. Furthermore, the connecting block 74 drives the alignment plate 75 to squeeze the stainless steel plate. The upper die base 1 is provided with a storage groove corresponding to the alignment plate 75. In view of the fact that two sets of deviation correction structures 7 are symmetrically arranged on both sides of the blanking component 4, the two alignment plates 75 can move and squeeze toward both sides of the stainless steel plate at the same time, achieving the effect of correcting the offset stainless steel plate, realizing the automatic deviation correction of both sides of the stainless steel plate. The rubber plate 710 and the buffer springs 79 play a secondary buffering role to protect the die components from being damaged by excessive impact forces; As Figure 5-6, when the driving component drives the upper die base 1 to continuously move downward until it is close to the top surface of the lower die base 2, since the connecting plate 78 and the counter-pressure block 812 are arranged corresponding to each other up and down, as the connecting plate 78 moves downward, it will press the counter-pressure block 812 downward. The counter-pressure block 812 presses the pressing plate 811 at the bottom downward. The bottom end of the counter-pressure block 812 is a slope, and the driven block 88 is a right trapezoid. The slope of the counter-pressure block 812 fits with the three-dimensional slope of the driven block 88, causing the pressing plate 811 to move downward and squeeze the driven block 88 to move in the direction of the rotating column 82. Since a support platform 81 is arranged on the top surface of the base 3, a folding plate 815 is arranged on one side of the support platform 81, and a first horizontal groove 816, a second horizontal groove 817 and a vertical groove 818 are formed on the surface of the folding plate 815. The pressing plate 811 drives the third slider 813 on one side to slide downward in the vertical groove 818, and the third slider 813 drives the fifth spring 814 at the top to stretch and store energy downward. And the driven block 88 drives the second slider 89 on one side to slide in the second horizontal groove 817, and the second slider 89 drives the fourth spring 810 on one side to stretch and store energy. As the driven block 88 moves, it drives the first rack 85 connected to one side to move. The first rack 85 drives the first slider 86 on one side to slide in the first horizontal groove 816, and the first horizontal groove 816 drives the third spring 87 on one side to stretch and store energy. The first rack 85 is meshed and connected with the first gear 84, and the first gear 84 drives the rotating column 82 to rotate 180 degrees, so that the correcting block 83 rotates 180 degrees around the rotating column 82 along the opposite direction of the pressing plate 811. A receiving groove corresponding to the correcting block 83 is formed in the upper die base 1. Since the limit correcting structure 8 is distributed in four groups at the four corners of the lower die base 2, the four correcting blocks 83 can rotate simultaneously to correct the other two sides of the stainless steel plate. At this time, the upper die base 1 and the lower die base 2 have not fully contacted for stamping. Therefore, before the punch punches the stainless steel plate, the deviation prevention structure 7 and the limit correcting structure 8 prevent the deviation of the four sides of the stainless steel plate. Through the cooperation of the slope and the right trapezoid, the downward pressing action of the upper die base 1 is converted into the limit correction of the four corners of the plate, realizing the transmission and buffering of force, ensuring the position of the plate in all directions before stamping, and significantly improving the success rate of stamping forming and the product quality; Such as Figure 8, after the punch finishes stamping the stainless steel plate, the ejector plate at the top is driven by the hydraulic rod contained in the ejector component 4 to slide upward in the processing groove, ejecting the workpiece. Since there is still excess stainless steel plate waste on the top surface of the lower die base 2, after stamping, the upper die base 1 drives the punch to move upward and return through the driving component, causing the upper die base 1 to drive the vertical connecting plate 91 connected to one side to move upward. Furthermore, the vertical connecting plate 91 drives the horizontal connecting plate 92 at the bottom to move upward. The horizontal connecting plate 92 drives the moving plate 921 on one side to slide upward in the sliding groove 924 opened on the surface of the side plate 923. The side plate 923 is fixedly connected to the lower die base 2, and the moving plate 921 drives the spring six 922 at the bottom to stretch and store energy. At the same time, the horizontal connecting plate 92 drives the long connecting plate 93 to move upward. The long connecting plate 93 and the pushing plate 95 are connected by multiple sets of compression springs 94. After the horizontal connecting plate 92 drives the long connecting plate 93 to move upward by half, the horizontal connecting plate 92 also pushes the pushing plate 95 upward. Therefore, the pushing plate 95 is not blocked by the side plate 923. The side plate 923 is flush with the top surface of the lower die base 2. The pushing plate 95 is pushed upward by the horizontal connecting plate 92. The bottom surface of the pushing plate 95 is flush with the top surface of the lower die base 2 and contacts the top surface of the lower die base 2. Thus, the pushing plate 95 pushes the waste material to the front end of the lower die base 2 through the elastic return of multiple sets of compression springs 94, facilitating the ejection of the waste material, which is beneficial for the stamping work of the next set of stainless steel plates. The pushing structure utilizes the return action of the upper die base 1 to achieve automatic cleaning of the waste material, avoiding the accumulation of waste material from affecting subsequent stamping work, reducing the impact on the mold and the workbench surface, and extending the service life of the mold; Therefore, as the horizontal connecting plate 92 moves upward, since the rack two 961 is fixedly connected to the base 3, as the long connecting plate 93 moves upward, the teeth on the rack two 961 mesh with the gear two 962, and the gear two 962 drives the rotating rod 963 to rotate counterclockwise. The rotating rod 963 drives the drawstring 964 wound around its surface to unwind. The drawstring 964 unfolds as the pushing plate 95 moves, without affecting the movement and pushing of the pushing plate 95. However, when the punch moves downward, the gear two 962 on the surface of the rotating rod 963 meshes with the rack two 961 and rotates clockwise. The gear two 962 drives multiple sets of drawstrings 964 on its surface to wind and reel in. Furthermore, multiple sets of gear two 962 drive the pushing plate 95 to move back to its original position. Multiple sets of compression springs 94 are compressed, so that the pushing plate 95 can be moved to both sides of the lower die base 2. Through the meshing of the gear two 962 and the rack two 961 and the winding and unwinding of the drawstring 964, it is ensured that the pushing plate 95 can be accurately positioned in different working stages, preparing for the next waste material cleaning, and further improving the automation degree and stability of the entire stamping process.
